'pplication filed July 1, 1921. Serial No. 481,870.

To all whomz't may concern A Be it known that I, WALTER T. CAMPBELL,

a citizen of the United States, 'residing at St. Louis, Missouri, haveinvented a certain new and useful Improvement in Spare-Tire ,Locks, ofwhich the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains'to make anduse the same.l

This invention relates to spare tire locks for vehicles of the kind thatconsists of a band which is adapted to be passed around a spare tire andthe carrier on the vehicle on which the tire is mounted, and a lockingelement for securing the ends of said band together in such a mannerthat an unauthorized person cannot remove the band from the tire andtire carrier which it surrounds.

One object of my invention is to provide a sparetire lock of the generaltype referred to that is equippedwith a novel means for preventing theband from cutting or chang the tire andfor preventing the lock as anentirety from rattling against the tire carrier. ,Another object isV toprovide a spare tire lock in which .the element that secures the ends ofthe band together also serves to hold the band in snug engagement withthe tire and out of contact with the tire carrier. Other objects anddesirable features of my invention will be hereinafter pointed out.'

To this end I have devised a spare tire lock that consists of a bandwhich is adapted to be passed around a spare tire andthe carrier on thevehicle on which the tire is mounted, an adjustable element arranged insuch a manner that when it is moved in one direction it will secure theends of the band together andalso draw the band into snug engagementwith -the tire and hold said band spaced away from 4the tire carrier,and

a concealed key-controlled device for locking said adjustable element.The band of the lock can be constructed in various ways withoutdeparting from the spirit of my invention, but it is preferably of suchdesign that one end portion of same laps over the other end portion andthe adjustable element previously referred to is mounted in one endportion ofthe band and is adapted to be forced through an opening in theother end portion of the band andl into engagement with the tire.carrier. The key-controlled device that is used for locking saidadjustable element can also be formed in various ways, so ilong as it isof such constructlon and arrangement that it cannot be actuated ortampered with by an unauthorized person.

Figure l of the drawings is a top plan view of a spare tire lockconstructed iny accordance with my present invention.'

Figure 2 is a side elevational view ofsaid lock. 65

Figure 3' is a cross-sectional view, taken on the line 3-3 of Figure 2;and

Figure 4 is a sectional view similar to Figure 3, with thekey-controlled locking device arranged in its inoperative position.

Referring to the drawings which villustrate the preferred form of myinvention, A designates the band of the lock which is adapted to bepassed around a spare tire m and the carrier y on the vehicle on whichsaid tire is mounted. Said band can either consist of a flexible,indestructible member, or it can consist of a plurality of rigid,segmental sections l and 2 connected together by a concealed hinge andof such shape that they conform approximately to the crosssectionalshape of the tire, as shown in Figure 2, the section 1 bein provided atits free end with an angular y-disposed portion la that laps over andextends transversely of the tire carrier, and the section 2 beingprovided at its free endfwith an angularly-disposed portion 2a that lapsover the angularly-disposed portion la on the section l of the band. Anadjustable element B is mounted in the free end portion of the I section2 of the band in such a manner that it can be forced througha hole inthe angularly-disposed portion la of the section l and then intoengagement 'with the tire car- 95 rier'fz so as to lock the free ends ofthe band together and also draw said band into snug engagement with thetire and hold said band practically stationary with relation to the tirecarrier, thereby preventing the band from cutting or chafing the tire orfrom rattling against the metallic tire carrier. In the form of myinvention herein illustrated thev element B consists of a screw arrangedvertically in an internally screwthreaded hole in the end portion 2a` ofthe section 2 and of such length that it can be moved downwardlyfthroughan aligned hole in the portion la of the section 1 and into engagementwith the tire carrier y, said screw being provided at its upper end with`a screw t river slot 3 or a non-circularshaped portion to which aWrench can be applied.

A concealed key-controlled locking device C is provided for locking theelement B in operative position, and while the particular constructionand arrangement of Saidilocking device C is immaterial so; far as mybroad idea is concerned, I prefer to use a locking device C thatconsists of a shiftable part arranged in a concealed pocket 4 in the endportion 2 of the section 2 and combined with a barrel lock D in saidportion 2 in such a manner that when the key'of the lock is inserted inthe barrel 5 of the lock and turned in one direction, the device C willbe moved into locking engagement with the element B, as shown in Figure3, and when said key is turned in the opposite direction, said lockingdevice will be moved out of engagement with the element B and into aninoperative position, as shoWn in Figure Lv vThe locking device lC canbe formed conveniently by an arm connected to the inner end of thebarrel 5 of the lock and so arranged with relation to the element B thatwhen said arm is swung into its operative position, as

shown in Figure 3, it Will'engage a fiat surwill be held so snuglyagainst the tire thatl it cannot move relatively to the tire, and

face 6 on the element B, and thus prevent said element from being turnedin either di'- rection. Accordingly, after thef element B has beenforced through the portion la of the section 1 and moved into engagementwith the tire carrier y and the locking de-V vice C has been Amoved intolocking engagement with said element, it Will be impossible for anunauthorized person to remove the band from the tire and the tirecarrier which said band surrounds. Moreover, as the locking device Cprevents the element B from Working loose, the band of the lock thus cutor chafe the tire, and it cannot rattle against the tire carrier. Inorder to assist the user in setting the element B in such a positionthat the flat surface 6 thereon will be arranged parallel with thelocking `device C, the portion 2a in Which said element B is mounted ispreferably provided with marks 7 as shown in Figure 1that align with thescrew driver slot 3 in the end of said element when the flat surface 6on said element is disposed in parallel relation with the locking deviceC.

A spare tire lock of the construction above described is inexpensivetomanufacture; it can be applied and removed easily; it locks the tiresecurelyto .the carrier and it will not cut or chafe the tire or rattleagainst the tire carrier. Y

Having thus described my invention, what l claim as new and desire tosecure by Letters Patent is:

l. A spare tire lock, comprising a band that is adapted to surround aspare tire and the carrier oir-Which the tire is mounted, and

an adjustable element for locking said bandv in operative position andfor moving said band relatively to the tire so as to hold it in.

2. A spare tire lock, comprising a band thatis adapted to be passedaround a tire and the carrier on Which the tire is mounted, and anadjustable element for securing the free ends of said band together andadapted to be moved into engagement with the tire carrier so as to movethe band relatively to the tire carrier and thus draw the band into snugengagement with the tire Which it surrounds.

3. A spare tire lock, comprising a band that is adapted to surround aspare tire and the carrier on which the `tire is mounted, an adjustableele-ment for locking said band in operative position for drawing saidband into snug engagement with the tire, and a concealed key-controlleddevice for preventing an unauthorized person from manipulating saidelement.
